Emergent entropy of exotic oscillators and squeezing in three-wave mixing process
S. K. Pal, P. Nandi, S. Ghosh +2
We demonstrate the existence of entanglement between the spatial degrees of freedom of a system of harmonic oscillators placed in the noncommutative Moyal plane ("exotic oscillator…
Simplifying 4d Harmonic Superspace
Dharmesh Jain, Chia-Yi Ju, Warren Siegel
We quantize super Yang-Mills action in harmonic superspace using "Fermi-Feynman" gauge and also develop the background field formalism. This leads to simpler propag…
Universal Pieces of Holographic Entanglement Entropy and Holographic Subregion Complexity
Sunandan Gangopadhyay, Dharmesh Jain, Ashis Saha
We propose that the definition of holographic subregion complexity (HSC) needs a slight modification for supergravity solutions with warped anti-de Sitter (AdS) factors. Such warp…
The 5d Superconformal Index at Large and Black Holes
P. Marcos Crichigno, Dharmesh Jain
We study the large limit of the superconformal index of a large class of 5d superconformal field theories and show it is given by the square of the partition fu…
Generalized entanglement temperature and entanglement Smarr relation
Ashis Saha, Sunandan Gangopadhyay, Jyoti Prasad Saha
We observe that in presence of excitation, a thermodynamic Smarr like relation corresponding to a generalized entanglement temperature () can be holographically obtained for t…
Holographic information theoretic quantities for Lifshitz black hole
Sourav Karar, Sunandan Gangopadhyay
In this paper, we have investigated the holographic entanglement entropy for a linear subsystem in a -dimensional Lifshitz black hole. The entanglement entropy has been analys…
